jQuery image hover color overlay

I can't seem to find any examples of this having been done anywhere on the internet before but here is what I am going to attempt to do...I'm trying to go about the cleanest possible way of laying this out.

So I have an image gallery where the images are all different sizes. I want to make it so that when you mouseover the image, it turns a shade of orange. Just a simple hover effect.

I want to do this without using an image swap, otherwise I'd have to create an orange colored hover-image for each individual gallery image, I'd like this to be a bit more dynamic.

My plan is just to position an empty div over the image absolutely with a background color, width and height 100% and opacity: 0. Then using jquery, on mouseover I'd have the opacity fade to 0.3 or so, and fade back to zero on mouseout.

My question is, what would be the开发者_如何转开发 best way to layout the html and css to do this efficiently and cleanly.

Here's a brief, but incomplete setup:

<li>
  <a href="#">
    <div class="hover">&nbsp;</div>
    <img src="images/galerry_image.png" />
  </a>
</li>

.hover {
width: 100%;
height: 100%;
background: orange;
opacity: 0;
}

So let's start with slightly simpler HTML:

<ul id="special">
    <li><a href="#"><img src="opensrs-2.png" /></a></li>
    <li><a href="#"><img src="opensrs-1.png" /></a></li>
</ul>

Here's my solution:

<style type="text/css">
#special a img { border: none;}
</style>
<script type="text/javascript">
$(document).ready(function() {

    $('#special a').bind('mouseover', function(){
        $(this).parent('li').css({position:'relative'});
        var img = $(this).children('img');
        $('<div />').text(' ').css({
            'height': img.height(),
            'width': img.width(),
            'background-color': 'orange',
            'position': 'absolute',
            'top': 0,
            'left': 0,
            'opacity': 0.5
        }).bind('mouseout', function(){
            $(this).remove();
        }).insertAfter(this);
    });

});
</script>

EDIT: With fast fade in, fade out:

$('#special a').bind('mouseover', function(){
    $(this).parent('li').css({position:'relative'});
    var img = $(this).children('img');
    $('<div />').text(' ').css({
        'height': img.height(),
        'width': img.width(),
        'background-color': 'orange',
        'position': 'absolute',
        'top': 0,
        'left': 0,
        'opacity': 0.0
    }).bind('mouseout', function(){
        $(this).fadeOut('fast', function(){
            $(this).remove();
        });
    }).insertAfter(this).animate({
        'opacity': 0.5
    }, 'fast');
});

Heres the whole thing

<script type="text/javascript">
$(function(){
        $("img").hover(function(){
                            $(this).fadeTo("slow",0);   
                            },
                            function(){
                            $(this).fadeTo("slow",1);       
                            });
});
</script>
<style type="text/css">
#lookhere{
    background-color:orange;
    width:auto;
}
</style>
Heres the html
<div id="lookhere"><img href="you know what goes here"></div>

It works and looks pretty cool. Nice idea.

Are you looking for something like this:

jQuery:

<script type="text/javascript">
  $(document).ready(function(){
    $("#images span > img").hover(function(){
      $(this).fadeTo("fast",0.3);
    },function(){
      $(this).fadeTo("fast",1.0);
    });
  });
</script>

HTML:

<div id="images">
  <span><img src="image1.jpg" /></span>
  <span><img src="image2.jpg" /></span>
  <span><img src="image3.jpg" /></span>
  <span><img src="image4.jpg" /></span>
  <span><img src="image5.jpg" /></span>
  <span><img src="image6.jpg" /></span>
  <span><img src="image7.jpg" /></span>
</div>

CSS:

<style type="text/css">
  #images span {
    display: inline-block;
    background-color: orange;
  }
</style>
